control arm

[Tricky1980]

OK, so i just bought a 91 coupe and it needed a tie rod.. so i changed that.. and now i went ot get it aligned and they tell me the driver side ball joint is bad but i was told its all ONE piece the lower control arm and ball joint? so if i buy a used control arm does this fix the problem OR???? im just a little lost
thx guys

They are stupid. You can press a new ball joint in. It's Moog pn# K9509.
